What This Value Measures
Fasting glucose is the sugar content in blood after several hours without food. It is an important value for assessing glucose metabolism.
Elevated Value
An elevated level may indicate impaired glucose utilization or diabetes mellitus.
Low Value
A decreased level (hypoglycemia) can occur, among other things, after prolonged fasting or with certain medications.
Note: Fasting value: no food for at least 8 hours before measurement.
Reference ranges are typical guide values for adults and vary depending on the laboratory, measurement method, age and sex — always compare with the range stated on your own report. A value outside the range does not automatically mean an illness, and a value within the range does not rule one out. The trend and overall picture are usually more informative than a single value. The doctor's assessment is always decisive.
